Resident Mike Townsend, 28, also made the list as a cofounder of HomeHero, a platform that matches seniors to trusted in-home caregivers.

Rubicon MD is a service that provides expertise and sharing between doctors.

“Our mission is to democratize the medical expertise,” said Addo, a 2007 Yale grad and a member of Harvard’s MBA Class of 2011.

Winning a place among the young crop of vastly talented professionals is a “phenomenal honor, especially within the healthcare space,” said Addo. “It’s really, really awesome.”

As part of Forbes 30 Under 30, Addo will take part in a summit next October that brings together everyone on the list in Philadelphia.

Now residing in Manhattan, Addo grew up in Middletown, along with his brother, Dr. Eric Addo, a Florida radiologist. His mother, Margaret Jordan-Addo, still lives in the city’s Wesleyan Hills neighborhood and remains active in the local community.

“She’s incredibly proud,” Gil Addo said.

Right now, the plan is to grow the service larger, beyond the current 25-state base, said Addo, who created the platform with Carlos Reines, also a Harvard MBA, and Dr. Julien Pham, who previously served on the faculty at Harvard Medical School, according to Addo.

The web-based platform connects doctor to specialist opinions online, saving one in three patients the time and expense of unnecessary specialist visits, Addo said.

“The best thing about this business, it’s the timing,” said Addo, who wants to make a meaningful change in healthcare. “There’s so much excitement.”
